Orange and `State of" New York,-have in vent'-,`

ed certain new and useful Improvements in.E Printers Furniture, of whichthe followingis a specification, reference being had therein to theaccompanying drawings.

This inventiourelates to furniture for printers use intended forlockingupprintingi forms in chases lor locking up chases inpressorcontracted to fill a greater or less spacein.

the chase or on; the press-bed,` andthus obviate the necessity of usinga large quantity of wood or metalfurniture when it is necessary to locka small form in a large chase or a small chase in a deep press-bed.

Extension furniture has been heretofore constructed in which two sidebars were conA nected by levers or lazy-tongs, and the side bars couldbe spread apart by changing the angular position of the connecting#levers By my telescopic construction of furniture I am enabledr to makelighter and better extensible furniture than any with which I amfamiliar. to make extensible furniture for printers use, I believe Ihavemade great improvements therein.

Figure 1 is a plan and partial section of a block of extensiblefurniture according to the general principles of my invention. Fig. 2 isa horizontal longitudinal section of one of the extensible bars. Fig. 3is an end View of the same. Fig. 4 is a plan of a chase with form lockedup therein and four blocks of extensible furniture applied to ll thespace between the chase and the pieces of rectangular furniture next tothe form. Fig. 5 is a'broken perspective viewshowing modification of oneof the extensible bars. Fig. 6 is a broken plan of part of saine. Fig. 7is a detail of holding-clamp. Fig. Sis a plan of form-chase and fourmodied extensionblocks. Fig. 9`is a side elevation of one bar, and Fig.10 a plan and partial section of a 5o block with spring-ratchet andpawlfcatch.

While notclairningto be the first Fig; is an end elevation of bar withratchet and pawl-catch.

v The chase Amay be any usual printers chase in which the form B is tobe locked in `any usual or desirable position. Such a form is usuallyplaced between rectangular pieces 'of furniture, as C C C C, whichfurniture incloses the type-form. Other usual appliances `of theprinting-office may b e substituted for furniture C, and my inventionmay be applied on the press-bed as well as inside the chase, as will bereadily understood by prac# vtallie piece is used, more weight will beinvolved than is usually necessary. A rectangular brass tube with awooden interior filler or fillers e makes a very good slide; but the'piece 2 may be solid.

Near one end of tube 1`I insert a fillerpiece 3, and a hole 4 extendsthrough the tube and` filler-piece. Cylindrical pieces or rods `5 areto4 pass through these holes 4 with a neat ht, so that the rods 5mayslide in holes 4, but not too easily. A similar hole 4 extendsthrough the slide2, and a similar rod 5 extends through this hole. Asecond extension-bar` 1 2, applied to the two, completes the rectangle,which may then be enlarged or reduced in either direction within thecapacity of the parts. Thus in Fig. 4 the upper block is shown with theside bars at about A the extreme ends of rods 5 5 and the telescopicbars 1 2 contracted, while the blocks at the sides of the ligure areshown with the telescopic bars extended, but adjusted nearer to eachother on the rods 5.

It will readily be understood that the bars 1 2 may be telescoped. It isnecessary that VIOO 3C' able length and width, "the two side bars 1 2 fto benew. x

means be provided for holding these bars exthe narrow end ofy notch 6will bind or com-"'"" press the part2.,againstfthetube 1. The'cyl inders7 of metal canbe placed by thevaction of gravity in the narrow or wideends 'of the notch. Thus when the bar 1 2 is extended to about thedesired 'distance 'the end "2 isy turned downward, and the cylinders 7will move tothe narrow end of the slot and wedge the parts firmly, Whileto release the wedge the end 1 is turned down'and maybe tapped lightlyto releasethe locking-detent. To pre-y vent `piece 1 from comingentirely out of tube 2, a'spring-pin 8 in piece 2 may be madeto engage ahole 9 in the tube when the parts g.

are sovfar extended as to permit such en` gagelnent. To push the piece 2back, this pin 8 may be pressed in byvany suitable instrument. j

The block D will be adj usted to the desirl being held in theirextension by their locking- `detent, and being held in parallelism andat the properv distance apart by frictional en'- The numeral 1l, Figs. 1and 2, shows a lock'- 'ing-quoin as applied vto tube 1*. Thisquoin l isa rectangular piece ofwo'od or metal have'V ing a mortise 12,throughwhich lapin 13 passes from the sides of' tube 1v to vkeep the quoinlfrom-falling out. Springs 14 bear on the .-pin and quoin and normallyretire the quoin within the tube. p between the quoin" 11 andfiller-pieceV 3, and 2 a polygonal hole in said caml permits it to be iturned by la suitable: key, the key being en-V i tered through a yhole16 in tube 1: This con- 1 structionvof camoperating on 'a q-uoin is not1 new, but the arrangement yof an extensible? quoin at the end of atelescopic bar is believed In Fig. 10 I have illustrated'a modificationwherein the slide 2*"is provided with arack 20. A spring-pawl 21,attached to"tube v1',

allows piece 2 to be drawn out of piece 1 freely. 'The pawl maybezpressed out of engagement with v the rack 2O4 by means .of a sleeve22, which incloses said pawl. `and. vis attached to d spring 23, whichspring is attached-t0 tube .1. The pawl 21 works through ahole in thetube l and lengages thelra-tchet 4on "slide 72.thu`s A cam 15is confinedin tube 1 -j forming the locking-detent. As a substitute for quoin 11.anextension-screw 31 may be ern'ployedg-said screw having a polygonalheadlto which a wrench may be applied to turn the s cfreyvdeut or in, andthus lock or unlock the block l) 1n its holding position.

e Stillfanother meansfonholding the slide 2l extended is rshown` inFigs.` 5, 6, and 7, inv

which case slide 2l hasnotohes 28 in opposite sides. i A fork 38, withits legs umade to t the notches, may be placed straddle of the notchedbar, one of the legs of the fork restingin asnotch ,if-alternate or` invboth notches if opposite. The fork, clasp, or locking-de tent 38 zwill'Vthus prevent the slide from being 'forced into tube 1. n f It will beunderstood from the foregoing that the extensiblejfurniture maybeexpanded to various 'sizes and used in various positions. The.v extremeextension of the length of bars l 2 permitssuch v'adjustment aswilllalmost ldouble the closed length ofblock DQ WhenA the rods 5 areremoved'froni bars 1 2, the

whole can be stored away very compactly.

A set of this extensible furniture for the inches, seven inchesextensible toabout thir- ;teeninches, and twelve -inches extensible toymore than twenty inches. Thus about three sizes A'of furniture willcover agreatvarietym foffuses. f f i A Where the rods 5 are long, morethan two `extension-barsmay be applied to a pair of rods. Variouslengths of rods will be supplied with sets of furniture; but,preferably,` these will all be of the saine diameter, Vand the holes inbars` 1 42jwill"correspondto such diameter. l i Y It will be understoodthat the tube 1 (and. islide 2fmay be'usedwithout the rods 5 for'narrowforms or to illout the blank columns,

r. orv that any 'number of the extensible pieces 1 2 may be used side byside without the rods -5. "A printer vwill readily find use fork thisfurniture. s
